UNITED STATES PATENT OFFICE.

HIRAM W. HAYDEN, OF WATERBURY, CONNECTICUT, ASSIGNOR TO HOLMES, BOOTH 81; HAYDEN.

lMPROVEMENT IN LAMPS.

Specification forming part of LettersPatent No. 17,680. dated May 9, 1865.

To all whom it may concern.-

Be it known that I, HIRAM W. HAYDEN, of Waterbury, in the county of New Haven and Stateof Connecticut, have invented an improvement in lamps for burning kerosene or other fluids rich in carbon and 1 do hereby declare the same to be fully described and represented in the following specification and the accompanying drawings, of which- Figure 1 is a side view, Fig. 2 a vertical section, and Fig. 3 ahorizontal section, of the movable part of a lamp-cap provided with my invention.

In the said drawings, A exhibits the cone or deflector, B the wick-tube, and G the wicktube and deflector holder or supporter.

In constructing the Wick-tube B, I make it corrugated lengthwise or with parallel grooves or channels extending down through it from end to end and on its inner surface, the same being as shown at a a a in Figs. 2 and 3. The advantage of such is that the oil, particularly when a heavy oil is used, is conveyed to and taken up to better advantage by the wick than it is when suchwick is encompassed and held by a cylindrical 0r flat-sided tube.

The burner in which my wick-tube is inserted is represented in the drawings. What I desire to secure by Letters Patent 1s- Making the wicktube corrugated or fluted with channels'in its interior surface, substantially as and so as to operate as specified.
